APPARATUS FOR DISTILLING TURPENTINE.

SPECIFICATION forming part of Letters Patent No. 790,635, dated May 23, 1905.

Application fue@ August 1,1904. serial No. 219,039.

To all whom, it Marry/concern:

Be it known that I, HARRY HIRsH, a citizen of the United States, and a resident of Eastman, in the county of Dodge and State of Georgia, have invented new and useful Im provements in Apparatus for Distilling Turpentinc, of which the following is a full, clear, and exact description.

My invention relates to apparatus for distilling turpentine and similar substances.

It has for its principal object the provisionV walls 11 and adome 12, both of which may be formed of riveted sheet metal, offering a proper resistance to the pressure which is to be applied. This retort may be supported upon a suitable base 13, of masonry or the like. At one side of the retort near the upper end of the cylindrical portion is shown a loading or feed door 14, while beneath it at the bottom of the retort is an unloading-door 15. These doors are bothset upon suitable casings 16, preferably consisting of castings secured tothe sheet metal, they being held in coactiorr with said casings by cross-bars 17, there being two of these shown in connection with each door, engaging at their ends in sockets 18, to which they may be secured by removable pins 19. Through each of the cross-bars is threaded a spindle 20, having at its outer end a hand-wheel 21, by which it may be rotated to turn the inner end into contact with thedoor and force it to a seat against the edge of the casing-opening, a gasket being provided, if desired, to insure a tight joint. Extending through the side of the retort at its lower portion is shown a pipe 22, also making a tight joint in its entry, by which a fluid under pressure may be introduced, the supply being controlled by a valve 23 in the pipe. This pipe 22 delivers to a coil or distributing' system within the retort, preferably consisting of a substantially horizontal pipe 24, located Iiust above the base. It is conveniently in the form of three sides of a rectangle, the open side of which is situated opposite the unloading-door, the rear corners being connected by suitable fittings. From each of the four corners rise substantially vertical members or pipes 25, which are con- `nected in pairs at their upper extremities by pipe-sections 26,thus forming double loops through which the fluid may flow. Along the inner side of each of the pipes within the retort are series of perforations 27, delivering the supply of the Huid within the retort. Connected with the retort are shown an automatic release-Valve 28 and a gage 29 for indicating the applied pressure. At the top of the dome may be secured a plate 30, from an opening in which leads a condensing-conduit 31, in which is a valve 32. This conduit terminates in a worm 33, situated within a receptacle 34:, through which a condensing liquid may flow.

The end of the worm is shown as delivering closed and the loading-door open, crushed` wood is introduced into the still to the desired amount. The loading-door is now also tightly closed and, with the valve 23 open and valve 32 closed, moist, dry, or superheated steam is supplied through the pipe 22 and and flows through the perforations into the retort, distributing itself among the contents. This supply is continued until the automatic valve opens, this indicating that the desired pressure has been attained, a suitable one for my purpose being that of sixty pounds. At such time the valve 32 is opened, relieving the pressure and allowing the introduced steam, carrying with it the vapor of the turpentine, to iow through the conduit 31 into the worm, where it is condensed and trickles down into the receiver. This is continued until the percentage of turpentine in the distillate indicates that the charge is exhausted, whereupon the valve 23 is closed and the door 15 opened, allowing the contents to be rapidly removed,

which prepares the retort for another charge. It should be noted that the absence of the run of the horizontalpipe directly opposite the door avoids interference with the removal of the material.

While presenting all the advantages of the ordinary turpentine-still, this apparatusv is extremely simple, permits great rapidity of Working, and readiness of loading and unloading. Moreover, it insures absolute freedom from contamination of the turpentine by the heavier tarry productions` which are not vaporized underthe temperature employed. It also obviates the danger of tiring the charge upon opening the unloading-door, this being liable to occur When the ordinary exterior method of applying heat is employed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A retort having Walls provided at their lower portion with a door, and a perforated supply-pipe extending about the interior of the retort and having a space between its ends opposite the door.

2. A retort having cylindrical side walls and a dome-shaped top, feed and unloading doors in the cylindrical portion, a supplypipe extending into the lower part of the cylindrical portion and forming three sides of a rectangle with the open side opposite the door, loops rising from the rectangular portion and extending to the dome, the pipes within the retort being perforated, and a condensingpipe leading from the dome.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing Witnesses.
